7 GROSSOVER-SWITCI-I.

To all whom it may concern:

Be it known that we, FRANCIS FINK and LEWIS F. Rex, citizens of the United States, residing at Lansford, in the county of Carbon and State of Pennsylvania, have invented new and useful Improvements in Crossover-Switches, of which the following is a specification.

The general object of the invention is to prevent the delay of trains or the tying up of traffic which has heretofore resulted from an obstruction such as a wreck on one of the main tracks of a railroad, and to this end the invention consists in a portable switch which may be readily transported to the vicinity of the obstruction or wreck and arranged at points to either side of the same, whereby, to permit of the crossing of a train, on the obstructed track and moving toward the obstruction, from the said obstructed track onto the unobstructed track and the continuing of its (the trains) journey on the last-named track until the obstruction or wreck has been passed when the train may move onto the obstructed track and proceed to its destination,

Other objects will appear and be better understood from the following description taken in connection with the accompanying drawings, in which,

Figure 1 is a plan of the device in operative position. Fig. 2 is a side elevation of the same a part thereof being broken away to disclose the clamp. Fig. 3 is a vertical cross section on the line 33 of Fig. 1. Fig. 1 is a similar view on the line 44 of Fig. 1. Fig. 5 is a bottom plan of the free end portion of one of the switch rails. Figs. 6 and 7 are fragmentary perspectives of the sections of the joint disconnected.

a designates one main track and Z) the other. 0 indicates generally, the switch forming the subject matter of the present invention. have shown the switch as connecting adjacent main tracks, although this application need not be adhered to, since it will be understood from what will appear later how the switch might be constructed so as to connect remote or alternate main tracks if more than two are employed. In this connection it may further be stated that, since only one switch is shown for connecting the tracks a and b it will be understood that a switch, similar in every detail to the switch shown except that it will be constructed reversely Specification of Letters Patent.

the track a, to pass from the latter again onto the track 6.

5 and 6 indicate the rails at one end'of the switch which are adapted to receive the rails 7 and 8 of the track a. Any preferred construction may be employed for efieeting this connection, such as by forming recesses 9 below the tread surfaces of the said rails 5 and 6. The rail 6 is recessed so as to bear on the outer face of the rail 8 of the main track a and its upper surface is inclined or tapered as shown at 10 in Fig. 2, so as to merge into the tread surface of the rail 8. The inclined or tapered surface 10 extends parallel with the rail 8 to a pointwhere the rail 6 curves outwardly from the rail 8 as indicated by 11 in Fig. 1. From the curved portion 11 the thereto, will be arranged on the side of the rail 6 extends substantially in a straight line.

The rail member 12 forms an extension of the rail member 6 and may be formed integrally therewith or connected thereto in a manner hereinafter described. This rail member 12 extends transversely of the rails 13 and 14c of the track 6 and has a curve as indicated at 15, whereby, to throw its free end portion 16 into a posltion parallel with the rail 13 which it receives, a recess being formed therein similarly to the recess 9 with the exception that it is formed in the outer side of the end portion 16 so that the side wall of the said recess will bear on the inner side of the rail 13. The portion 16 is tapered or inclined as shown in Fig. 1, so as to merge into the tread surface of the rail 13. The rails 6 and 12 form one side of the switch and extend parallel with the rail 5 and rail 17 which forms an extension of the rail 5 and may be formed integral therewith or otherwise connected thereto as hereinafter described. The rail 5 has a portion curved as shown at 18, so as to throw the rail in a direction transversely of the track a whereas the rail 17 is curved as at 1.9 so as to throw the free end portion 20 parallel with the rail 14 of the track 6. A recess is formed in the inner side of the free end portion 20 of the rail 17 so as the sidewall of the recess will bear on the outer side of the rail 14, the portion 20 having an inclined surface extending parallel with the rail 14 of the track 6 and merging into the tread surface of the said rail 14.

If the rails forming each side of the switch be integral throughout, suitable're cesses will be formed to receive the rails 8 and 14 at points where the sides of the switch cross the said rails. If, on the other hand each side of the switch is made up of sections, such as shown, the connection will be like that shown in Figs. 6 and 7 where the section at corresponds to the. sections 12 or '17. In this connection 21 indicates an undercut or recess extending obliquely of the section and transversely thereof. The oblique walls (shown by dotted lines in Fig.

6 and designated by the numeral 22) of the "recesses of the sections 12 and 17 extend parallel with and bear on one face of the rails 8 and 14. The section (2 in Fig. 7, corresponds to the inner end of either section 6' or 18. In this connection 23 indicates a f right-triangularshaped reduced end whose inclined side 24 extends parallel with the oblique side 22 when the parts are connected as shown in Fig. 1. In this connection it will be observed that a shoulder 25 results 1' from reducing the end portion 23, the said 25 shoulder forming an abutment for the connected rail section. The object of reducing the end portion 23 is to provide an even tread surface at the joint. The parts, as 'f'shown in Figs. 1 and 4, may be connected by passing a bolt 26 through alining openings in the sections and securing the bolt by means of a nut 27. The head 28 of the bolt being arranged in a countersunk opening so Ta: to prevent an uneven tread surface. Since the inclined side 24 is parallel with the side 22, the side 24 on each of the sections 11 and 18 will bear on the sides of the rails 8 and 14 of the tracks a and b oppositely from the ""sides of saidrails upon which the inclined sides 22 bear.

29 indicates truss or tie rods which extend transversely of the switch and connect the opposite sections thereof. By preference i'these truss rods have their opposite v ends screw-threaded as at 30 and pass through openings in the sections of the switch',-rsuitable securing means such as nuts 31, being screwed onto the screw-threaded portions 30. As shown in Figs. 3 and 4 suitable fillets '32 are interposed'between theside Walls of the recesses 9 at the free ends of the rails of the switch and webs83 of the rails. The provision of these fillets prevents wabbling or displacement of the free ends when the clamp screws 34 are tightened as shown in Figs. 3 and 4. The clamp screws 34 form part of a clamp 3.5-which has one end por tion adapted to engage the base flange of the track rail and its opposite end portion turned upwardly as at 36 and pierced to receive the clamp screw 34. The clamps 35 may be arranged at points where the switch rails abut the rails of the main tracks a and tadjusted as shown in Figs. 3 and 4.

Although I have shown and described one embodiment of my invention it is to be vunderstood that I'am not to be limited to the specific arrangement and construction of parts since various changes will be made, within the scope of the appended claims Without departing from the spirit or sacriticing any of the advantages of the invention. What we claim as new is: The combination with main'tracks, of a cross-over switch for connecting the main tracks and comprising sectional rails, said sections having their adjacent endsrabbeted and extended and overlapped to lie in the same plane at the point of intersection with the adjacent rails of the main tracks, the adjacent ends of the sections being cut away obliquely and forming Walls spaced apart to provide a receiving groove for the main track ways, means for holding the rails of the cross-over spaced apart, clamping devices holding the free ends of the rails of the cross-over to the adjacent portions of the main track rails, and filler blocks interposed between the main track rails and the adjacent portions of the cross-over switch rails.
